How to apply:

LOCTITE 3090

1. PREPARATION

Cleaning
It is recommended to use LOCTITE SF 7063 to degrease and clean surfaces prior to applying the adhesive.

Priming
To improve adhesion on difficult to bond plastic surfaces, apply LOCTITE SF 7239 or LOCTITE SF 770 to the bond area by brushing or dipping. Avoid applying excess primer. Allow the primer to dry.

Activation
If cure speed is too slow, use appropriate activator LOCTITE SF 7458 (see cure speed vs. activator graph in the TDS). Apply activator to one bond surface by spray, brush or dipping (not to primed surfaces). Allow the activator to dry.

Mixing
with static mixer
Before mounting the static mixer onto the cartridge, push out a small amount of product to equalise pistons. Mount static mixer and push some mixed product out. The static mixer will then dispense correctly mixed product.

2. APPLICATION

Apply adhesive by drop or bead to one of the bond surfaces (not to activated surfaces).

Equipment
Recommended dispensing equipment:

  • For precise dispensing of small amounts of adhesive use dispensing needles
  • Spare static mixers: IDH 1453183

3. ASSEMBLY

Assemble the parts immediately. The parts should be accurately located, as the short fixture time leaves little opportunity for adjustment. Bond should be held fixed or clamped until the adhesive has fixtured.

Hint
If necessary excess product can be cured by activator LOCTITE SF 7458. Spray or drop activator on excess product.
